건설-IT융합 기술을 위한 터널 환경에서 무선 메쉬 네트워크를 이용한 실험적 성능 검증 = Empirical Evaluation of Wireless Mesh Networks for Construction IT in Tunnel Environments

다국어 초록 (Multilingual Abstract)

This paper draws performance results through comparing WMNs’ methods when the WMNs are used in tunnel construction sites. There are many advantages of WMNs : lower cost. easy to network maintenance, robustness and reliability within RF-ranges. As a result, using the WMNs would be suitable to employ as a network infrastructure for the construction sites. This paper evaluates the performance of WMNs which we have installed in a tunnel construction.
Through the performance results, we conclude the performance of data throughputs gets lower when we perform the network in tunnel environments. We make attempts WMNs’ two major methods which are SISC(Single Interface with Single Channel) and MIMC(Multi Interface with Multi Channel) to figure out which method will be better for the construction sites. Through the experiments, the WMN based on the MIMC method was comparatively suitable in network performance aspect for the tunnel sites.
